SPECIFICATION forming part of Letters Patent No. 504,577, datedSeptember 5, 1893.

Application filed November Il, 1892. Serial No. 451,677. (No model.)

To all whom t may concern.-

Be it known that I, JOHN O. GREENFIELD, of Forreston, in the county ofOgle and State of Illinois, have invented certain new and usefulImprovements in Turling Implements; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,suoli as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification.

My invention relates to an improvement in turfing implements; and itconsists in the novel combination and arrangement of parts which will befully described hereinafter, and more particularly referred to in theclaims.

The object of my invention is to construct an improved implement for usein making rugs of that class in which the surface of the fabricforming'the body of the rug is covered with projecting loops of thread,cord,tape and the like, whereby the desired work may be accomplishedvery rapidly an d with precision.

Referring to the accompanyingdrawings,- Figure l is a perspective viewof my improved implement. Fig. 2 is afront elevation of the same. Figs.8 and et are enlarged de tached views of the feeder. Figs. 5 and 6, aresimilar views showing the pivotal connection between the feeder andframe. Fig. 7, is an enlarged view of one of the needles shown partly insection.

A, designates a vertical standard upon the lower end of which is thefoot B, moving on rollers O, which form the support for the machine.Extending upward from opposite sides of the upper end of the standard A,are the frame sides D, and secured between the upper ends of these sidesis the handle or pressure knob E.

.Iournaled in the sides D, near their lower ends is the double crankshaft G and loosely connected to the cranks of this shaft are thedepending needles H which reciprocate through the guide I, near thelower end of the standard A. Secured on the shaft G, between the sidesD, is the pinion J, which meshes with the gear wheel K, locatedimmediately above it on the operating shaft L, provided with a crank asshown. Upon the opposite end of the shaft L, from the crank is the wiperM, for the purpose presently to be stated.

N, designates a lug projecting from one of the sides D for the purposeof supporting the thread or cord feeder. The latter consists of theplates O, and P, the former being constructed with the transverselyextending angular arm Q, while the plate P, is constructed with thesimilarly formed flat arm R. The plates O, and P, are pivoted togetherat O', while the rearwardly extending portion of the plate O, ispirotally secured to the lug `\l. The rear end of the plate P, is turneddown below the similar end of the plate O, as shown at P, while both ofthese rearwardly projecting plate ends extend into the path traveled bythe wiper M, when the shaft upon which the latter is mounted isrevolved. The outer edge of the arm R, extends slightly over thevertical edge of the angular arm Q, thus forming a stop when plate P isturned on its pivot. Confined between the arms Q, and R, is the springS, which holds the same normally apart and with a space between theengaging edges of the arms Q, R, above referred to. The thread or cordis passed downward from the spools T, on the supports T', to the feederwhere it enters the same through the open space between the arms Q, andR, of the plates O, and P. The thread then passes downward throughperforations in the horizontal plate of the arm Q, as shown and fromthence downward to the needles. The spools are conned on said supportsby nuts or heads on the ends of the latter as shown. Projecting downwardfrom the plate O, is the arm U, to the lower end of which is secured thedepending end of the spring V, supported by the frame side D. Thisspring' normally extends forward or outward from the frame so that whenthe feeder is turned on its supporting pivot, the said spring yields toits movement but when the feeder is freed it returns the latter to itsnormal position. This spring governs the position of the whole feederwhile the spring S, serves to hold the arms Q, and R, apart.

In operation when the needles are raised by revolving the gear wheelsone end of the wiper M, engages the depending end P, of the plate P,carrying the said end upward and the outer end of the said plate and armR, downward compressingthe spring S,so that the arms Q, and R, are inengagement thus binding the cordwhich passes betweenthem tothe needles.In this way a secure grip is obtained on the cord and the feeder beingturned bodily on its supporting pivot, by the continued movement of thewiper M, draws the cord downward toward the needles. 1When the wiper M,has been revolved sufficiently far to disengage the said end the springV, returns the feeder to its normal position while the spring S,immediately separates clamping arms Q, R and thus releases the feederfrom its hold on the oord or thread. The outer end of the feeder isturned downward by this operation as will be understood drawing downwardtoward the needles a sufficient amount of thread to supply one stitch orloop for each needle. The downward movement of the needles is notsimultaneous with the vibration of the feeder but rather follows themovement of the latter so that for each stroke of the needles a supplyof thread or cord has been drawn down by the feeder. The needle upon itsdownward course through the material carries with it the thread or cord.When the needle begins to retract, the cord forms into a bow or loop,the springy tendency of the same when turned into a U serving to draw itthrough the needle, or rather allow the needle to slip upward thereon,thus leaving the loop upon the under side of the material andaccomplishing the desired result.

By employing two needles the work may be accomplished very rapidly astwo rows of loops or stitches are placed at the same time.

It is my purpose to provide each implement with two or more feedersvarying in size to accommodate and feed carpet rag material or tinecord, and as the feeder is removable from the frame the change can beeffected with very little trouble.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a turng implement, the combination of a frame, a needle, a shaftfor actuating the same an operating shaft which imparts motion to thefirst named shaft, a wiper secured to the operating shaft, a springretracted thread feeder pivoted between its ends to the frame andintermittently engaged at its rear end by the wiper whereby the same isoscillated,substantially as shown and described.

2. In a turtingimplement, the combination of a frame, a needle, a meansfor actuating the same, a spring retracted feeder pivotally secured tothe frame consisting of two plates pivoted together, laterally extendingarms on their ends, a spring for holding the said arms normally apart,and means closing the arms together and oscillating the feeder,substantially as shown and described.

3. In a turng implement, the combination of a frame, a needle, a wiperand a means for actuating them, plate O pivoted to the frame, spring Vengaging the same, plate P pivotally secured to plate O having dependingend P', laterally extending arms Q, R, and a spring interposed betweenthe same for holding them normally separated, the plate being oscillatedand the arms closed together against said spring by the said wiper,substantially as shown and described.

In testimony whereof I afx my signature in presence of two witnesses.
